Best program for slideshows

[Goose]

Im going to show the pictures of my last vacation to my friends and am still in need for a really good slideshow program, that also uses effects to actually change the pictures.
Is Acdsee really best for it?
thanks

Go grab Picassa from Google.

It's by far the best photo management / sharing / slideshow program that I've ever used.
